Unable to Log into SM Admin UI

I get the login page when i navigate to the SM WAM UI URL, but when i enter the siteminder creds and click submit, it just brings me back to the login page and empties the userid/pw fields. I know the creds are correct because If i enter incorrect creds, i get an 'invalid credential error'.

There were no issues with installing the prereq or admin ui installers. I also ran smreg and xpsclientreg. The only line i see in the logs when i try to log in is: '[DEBUG] com.ca.siteminder.directory.AdminPartition [] - Creating entry uid=siteminder,ou=Administrators,ou=Siteminder...' Policy store is SQL Server.

what you see in server.log file? is IAM loading sequence (around 36 I guess) successful? Sometimes policy server takes time reading policy store and if WAM UI service is brought up during that time, Policy server will not serve request.

1) Wait for policy server to be ready (it will show message in smps.log that it is ready)

2) Stop WAM UI service completely

3) Start WAM UI server and watch server.log. When you see message all startup sequences are completed, try to login. If that does not work, you might want to enable access logs and post server.log for further troubleshooting.
